Comment: A bartender for example has the obligation not to serve a customer he views as inebriated. If he continues to serve that person, he could be legally liable for the collateral damage that inebriated person does. That’s not only true legally in our system of laws, but also a religious truth

This is strictly of faith, as defined by the First Vatican Council (1869-1870):

If anyone says that divine revelation cannot be made credible by external signs, and that therefore men and women ought to be moved to faith only by each one’s internal experience or private inspiration: let him be anathema.
